SPECIFICATION forming part of Letters Patent NO. 345,119, dated July 6, 1886.

Application tiled Dceembcr, 1885. Serial No. 18l,81l1. (No model.)

To all whom it may concern:

Beit known that I, PETER CooL, a citizen of the United States, residing at Manhattan, in'the county of Riley and State of Kansas, have invented certain new and useful Improvements in Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which-it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures ot' reference marked thereon, which form a part of this specification.

Figure l of the drawings is a vertical sectional view of the lock embodying my invention. Fig. 2 is a transverse vertical section on line x a', Fig. l.' Fig. 3 is ahorizontalsection on line i/ y, Fig. l. view showing a modification.

This invention has relation to mortisc-locks; and it consists in the construction and novel arrangement of parts, as will be hereinafter set forth, and pointed out in the appended claim.

In the accompanying drawings, the letter- A designates the latch-bolt, which is provided with a double bearing, G, in its shank, so that it can be reversed. The back portion ot' this bolt engages a stud, H, on the upper portion of the eight-lever B, said stud being located forward ot' and above the fulcruni-pin F, on which the weight-lever turns.

J is a partition-piece forming a part of the lock-case, which is located below the weightlever and serves to limit its downward movement and to separate it from the lock-bolt L below. An opening, I, is made through the weight-lever to allow the tumbler O to be placed in position. This tumbler is provided with wings or lugs D, which operate against a bearing, V, of the weight-lever, and has a square opening, E, for engagement with the knob-spindle.

VK indicates the key-hole, and L the lockbolt, which is made with a rack formation on the side next the key-hole, as indicated at a,

Fig. 4 is a similar' Openings c are made in the case-walls P Pv for the journals of the revolving night-latch M, which consists of ailtongue,d,on a journaled bar, e, which is provided with the operatingarms f. In order to make room for these small arms, the case-walls P are countersunk or recessed around -the openings c on the outside, so that when the lock is applied there will .be no projection requiring eXtra carpentry.

When the lock is to be inserted in a mortise, the same stem, Q, is employed, this piece being inserted in a threaded aperture or bearing in the journal-bar e, which is provided therefor.

This lock is easily. reversed, it boing necessary only to turn the latch-bar Aupside down,

so that the bevel will be turned to the opposite side.

Having described this invention, what I claim, and desire to secure by Letters Patent, is-

In a lock, the combination, with a casing having its bottom inner wall provided with 4the double-bevel bearing S, of the lock-bolt L,

having its inner end provided with a rackextension to engage the key, and at its opposite upper edge provided with a stop-lug, I, and on the lower opposite edge a double-bevel projection engaging the bevel-bearing S, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

PETER COOL.
